Specification of Letters Patent.

Patented Mar. 21, 191s.

Application filed May 29, 1912. Serial No. 700,386.

T all whom it may concern:

Be it known that 1, PAUL HANNAGAN, a citizen of the United States, residing at Lawrence, in the county of EsseX, State of Massachusetts, have invented a certain new and useful Improvement in DumpinglVagons, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention comprises an improved construction of frame providing for hanging the wagon-body low down between the wheels; also, permitting of propulsion by horses or motor, as preferred.

It further comprises novel means of raising and lowering a tilting wagon-body.

The invention is illustrated in the drawings in which,-

Figure 1 is a side elevation of a wagon containing one embodiment of the invention. Fig. 2 is a plan thereofwith the seat and portion of the front platform and wagonbody broken away. Figs. 3 and 4 are views on the order of side elevations chiefly intended to show the wagon-body -in partlytilted and fully-tilted positions, respectively. Figs. 5 and 6 show in side view and plan a second embodiment of the portion of the in vention relating to the means of raising and lowering a wagon-body. Figs. 7 and 8 show another embodiment.

The wagon-frame comprises upper sidebars 1, 1, which preferably are channel-bars, one or more cross-bars joining said side-bars at the front end of the frame and one of which may constitute the front-end crossbar 2, lower side-bars 3, preferably of channeled form, upright tie-bars 4, 4 4", etc., connecting together the upper and lower side-bars at each. side of the frame, inclined truss-bars 5, 5 also extending from the upper side-bar to the lower one at each side of the frame and the trussbar 5 being bolted to upright tie-bar 4, a front-end cross-bar 6 between the front ends of the lower side-bars, and cross-bars 7, 7, between the lower side-bars. The upper and lower sidebars are flanged at top and bottom, to secure strength and stiffness with comparative lightness. Preferably, the cross-bars 7, 7, are composed of flat stock having the ends thereof bent up outside the lower sidebars 3, the said cross-bars being placed against the under edges of the lower sidebars 3, and secured in place by bolts or rivets 8, 8, passed through said bent-up ends and the lower side-bars. At 9 is a cross-bar at the rear of the wagon-frame, extending from one lower side-bar to the other, and having the wagon-body 10 mounted thereon by straps or bearings 9 connected to the rear portion of the wagon-body and fitted to said cross-bar with capacity to turn thereon. At11 is a drop-axle, extending across beneath the lower side-bars, and secured by its end-portions to the said lower side-bars. 12, 12, are therear wheels, they being mounted upon the opposite ends of the said drop-axle. The lower sidebars 3 rest upon the said drop-axle of the said rear wheels, and are supported thereby. The said lower side-bars, combined with the upright tiebars 4, 4, 4", etc., and inclined truss bars 5, 5, constitute an inclosing frame for the portion of the wagon-body which hangs down between the upper side-bars and below\ the latter. The front upright tie-bars 4 area little in front'of the front end of the wagonbody. The upper side-bars 1, 1, project some distance to the front, beyond the front end of the Wagon-body and the said depending framework. The upper horizontal portion of the framework therefore projects at the front end of the vehicle, and it may project to any desired length. Beneath the forwardly projecting portion is thereby provided a space within which may be located a truck with wheels and a pole or shafts, etc., for hitching horses, or a self-propelling tractor, or an engine or motor 13 of any approved character can be attached directly to the overhang, thereby permitting the body of the wagon to be located close to the ground in consequence of locating the power mechanism entirely at the front end of the wagon-body instead of underneath the same. In Figs. 1 to 4 the shaft 13 of said engine or motor carries sprocket-wheels 13*, 13',

from which sprocket-chains 13, 13, pass to sprocket-wheels 13, 13 on wheels 12, 12, for operating the latter to propel the wagon.

The elevation of the overhang, as shown in Figs. 1, 3 and 4, provides also for free turn- 1 ing Oftlfe front truck under the body-frame when horses are used. When horses are not used, auto-wheels, as at 14, may be convenientlymounted in connection with the over carriage with the wagon-body 10 by means arranged to not to first raise the front end of the said body high enough to permit the carriage, or parts carried thereby, to enter beneath the body or parts in connection therewith, and then cause movement of the earring" toward the rear end of the vehicle under the body, to further tiltthe wagonbody and effect the dumpin The specific means and manner of combining the corringe with the body to secure the described mode of operation and produce the desired results may vary in practice. In Figs. 1 $0 4: the carringjc is equipped with toothed pinions 1T, 17., 2, the number of which may very, fixed upon a shaft 18, extending iiIuliSVQTSt 'y of the carriage and mounted at its ends in l: urings in the si l -pieces of the cur-ringer the said toothed pinions meshing with .tmthcd r: ClCS if}, '19. attached to the u'zzgon iel n Two of such pinions and 2t coir opondingg z'nnnher of rocks are shown her Nil. ,5 may in practice employ a single For in raising the trout end of the and rack, or more than two. the pu'rp-ci wrap embody high enough to pcru'iit the car ringe, or parts in connection therewith, to under the wogoirhody, or parts in con ncctimi with the latter, the said rocks 19, 19, are extended \crticslly upon the front end oi the \\'fil'f irlfl ily shown. Suitable provision is in: lo in practice for rotating the shaft 18, eitl" r by hand or by power, desired. Herein, for such purpose, the said shnl't has fixed upon one end thereof it toothed wheel, 90, with which meshes n can rier or idle toothed wheel, 21, fixed to which is :1 second tootheo wheel, 22, which meshes with n toothed pinion on a shaft 24: having :1 suitable crank and handle 25. The said toothed wheels 21, 2 23 and shaft 2% are mounted on carriage 15. The described gearing between the crank and the pinion shut t SClYlfS to compound or increase the power; Other convenient mechanical arrangements for rotating the shaft 18 may he en'iplo -{cd in \iu'ncticc, such for instance as a worm and norm-gear: As the shaft 18 and pinions ll, 17, are rotated, the front end of the wugoirhody is elevated Suitable provisions are made in practice. for preventing the piuions l'roni springing out of mesh with the raurlcs. ln the present instance, plates 2t 26, are mounted loosely upon the pinionshaft at opposite sides of each pinion 17. These plates carry projections, which cuter gromcs in the sides of the reels its l'fil'llTk lliilll in Fig i. Fin-id projections; i'ruty consist of simple pins or the like, or may carry anti-friction rolls. As the front end of the body is swung upward, carriage shifts its position upon the supportin bars, in consequence of the engagenie described with the grooved sides of racks, and as soon as the wagon-hoe been raised for enough to permit the rings to enter beneath such end, the ca rringe is drawn under the elevated lower front corner of the latter, as in 3. I prev in connection with the carriage means oi supporting the pressure the carriage passes Hider the body, and during the con tinued movement the cnrriu ge along under the body toward the rear end of the The said means preferably comprises disks or rolls 2'7, 27, mounted upon the carriage. In this instancethe said rolls are mounted loosely upon the shaft The number thereof may vary from one to more tlmn two, and the location of such rolls or the substitutes therefor may vary, 1 do not limit mysell to mounting them upon the shaft 18. he continued rotation of the shaft causes the carriage to trowel toward the rear end of the wagon as a consequence of the engagement of pinions ii", 1?, with the portions of the rocks l9, 19. which extend along under the bottom (it-the wngonhody. In doing so it elevates more ind more the front end of the wagon-ind i i some around the rear crossbar r. i it is pivoted, as in at, until the ho; has been tilted to the desired position.

The. body will be prevented from o turning hnchwnri'lly by reason of the gagcnni-nt of the projections of the 1' 26 26, in. the gror: 6 ot the rn' lis, and lurther, of the. engagement o? the rolls it 13, with the upper flanges of the upper side bars 1, l. The weight of the upliflnd por-- tion of the wngczrbody (Fig. l) will tend to cause the carriage to travel forward toward the front end of the wagon. The speed of the return niny be controlled oy means of handle 25, or the return of the can riagc may be caused by n reverse turning movement of the shaft 18 and its pinious. The movement of the. carriage forward to the front and of the wagon will lower tho front end of the wagon-li o l v, and draw it down in (use it should not more readily, until the position shown in Fig. 3 rez'uzl'icd, and thorn after the arriage has passed in front ol the front corner of the body, the continued. rotation of shaft 18 will lower the wagoulmdy or permit the some to lower wholly to its position in Fig". 1 in consw quence of the notion of the pinions in the upright portions of the racks upon the fromv of the wagon-Mid Thereby the wagon body is lowered gradually and easily. under A pawl or dog 29 engages with one of the toothed wheels to lock the body in any position of complete or partial elevation. This locking means enables the body to be used in a partly elevated and inclined position. if desired, and prevents the weight. of the uplifted wagon-body from forcing the *arriage forward except when desired.

The carriage 15 is shown in Fig. l as 'adapted'to pass forwardly partly under a seat 28 for the driver. In other constructions. With a lower body, and with a lower carriage, the seat may be mounted upon the carriage itself.

Figs. and sho'v an embodiment of my general invention relating: to the. raising and lowering: mechanism. in which in lieu of the toothed pinions 1T. 17. and racks If). 15). of Figs. 1 to 4 a chain 30 is connected by one end thereof with the transverse shaft is upon the carriage 15, the said chain extending down from the. said shaft and rear ward under the Wagon-body and its other end being connected with the latter at 30. Fig. (i. or to some other convenient point of attachment. which might be rear cross-bar l): a toothed pinion 17 being fixed upon oneor each cod of said transverse snaft l8. and a rack 19 being fixed upon one or each upper sidebar I. The said pinion ii is enga n-d by an actuatingpinion I? on a transverse shaft l7. When the carriage is in its forward positioninwlnch the rolls or disks 27. 27. on the transverse shaft 18 are in contact with the front end of the wagon-body. the pinion 17 is entirely at the front of the front end of the rack 19*. In this position of the carriage. the chain 30 being unwound from the said transverse shaft 18. the wagonbody oc upies its lowered position. If now the UTIIISVQI'S'. shaft 17 be rotated so as to rotate the shaft 18, chain 30 will be wound upon the latter. and the front end of the wagon-body resting upon the chain will be lifted. The rolls or disks 2". 27. will roll against the surface of the front end of the wagon-lmd) as such end rises. holdingzpinion 17 forward of the rack. When. however. the lower front corner of the wagondvnly rises above the rolls or disks 2.7. 27. the pull on the chain will cause the carriage to move rearward along the ripper sidebars l. l. and pinion 17 will enter into engagement with the rack. The engagem nt of the pinion with the rack will operate. to cause. the ca rriage to continue its rearward movement. 'so as to carry the rolls or disks 2T. 31'. in under the wagon-body and tilt the latter upward. As this action proceeds the chain 30 will wind upon haft 18*. By turning. niovcment of the shaft I7 in the. other direction. causing shaft. 18 and pinion lT to turn in the reverse direction. the carriage will be caused to return to 'ard the front end of the wagon, thereby lowering the wagon-body.

In this turning movement the chain 30 will be paid out at a rate corresponding with the forward movement of the carriage. As the rolls or disks 1T. .27. pass the lower front comer of he wagoirbody they will cease to support the latter. which will then be supported by the chain 30. and as a result of continued unwinding of the latter the wagolnbody will be lowered to its normal i msition. The weight of the. uplifted wagon bod) may be relied upon to etlect. the return of the carriage to the front end of the wagon under control of the operator, such control dete mining the rate of descent of the wagon body into position again.

Figs. 7 and 8 show an embodiment of certain of the principles of the invention in which the fixed rack 19". and the pinion 17. are dispensed with. the tilting action being secured wholly by means of th chain 30, and disks 2T. 27. the construction otherwise being similar to that of Figs. 5 and (i. In the ease of this embodii'nent the winding of the chain upon the shaft on the carriage will operate first to raise the wagon hody. and then as soon as the front end of the lat' ter has been lifted high enough to permit. rolls "27. 27. to pass under the same the continned Willtliilpflll'l of the chain will open ate to pull the carriage rearward under the wagon-body. thereby completing the tilting of the latter.

The specific construction may be further varied in different respects without necessarily involving a departure from the spirit of my invention. For instance. I may make use of one or more racks at the front end, only. of the wagon-body, to coi'ipr-rate with a gorresponding number of pirions in lift inn such end. to admit the carriage. and. may utilize one or more chains and winding means therefor to ether-t the rearward movement of the carriage. i may employ in the carriage a gufrh pulle mounted on a shaft or other support forward of the winding shaft. to and around which puller the chain passes on its way to the windingshal't.
